Dual clutch systems are entirely different from automated manuals. Automated manuals like the i-Shift are merely manuals with an electric clutch and actuator that mimic the driver changing gears, not always very satisfactorily. A dual clutch automatic like VAG’s DSG or Ford's Powershift has two clutches and two sets of gears on separate shafts that pre-select up or down. Of all the dual clutch boxes, I think Ford/Getrag's Powershift works best. Prior to the Powershift the Fiesta had a 4-speed torque converter auto, like the Mazda 2’s.
